Definitions

  • the invention relates to an RF-shielded coupling part for a cable, in particular a multiwire cable having a shielding sheath within its jacket; in a contact area stripped of the jacket, the cable is in an electrically conductive connection to a metallic shield. Cables of this type are used, for example, with data processing systems.
  • An undesirable aspect of such cables is that, with known coupling parts of cables used with data processing systems, radio frequency interferences are received or radiated.
  • this feature is achieved in that a metallic stopper is pushed onto the jacket surrounding the circumference of the jacket and is secured in position in a direction longitudinal to the cable, in that the contact area is solderlessly clamped in between the stopper and either the jacket or the shield, and in that the stopper sits in a close relationship to the slotless shield in its entire circumference and the shield is held in a force-fit connection at the stopper in the longitudinal direction of the cable.
  • This construction prevents the formation of a radio frequency window between the cable and the shield, because the metallic stopper surrounds the jacket and is in turn enclosed by the shield.
  • the contact area of the shielding sheath is simultaneously contacted. Even if the sheath in its contact area is shifted at the circumference. The shield is tightly direction of the cable.
  • the FIGURE shows a sectional view of an RF-tight coupling part according to the invention.
  • a cable 1 comprises a plurality of wire strands 2 and a shielding sheath surrounding the wire strands 2, which runs within a jacket 4. At the end of the cable, the jacket 4 has been removed, so that a contact area 5 of the shielding sheath 3 is exposed.
  • a stopper 6 consisting entirely of metal is pushed onto the jacket 4.
  • the stopper 6 comprises a head portion 7 and a neck portion 8 turned away from the contact area 5.
  • a collar 9 extending around the head portion 7 is formed, which is adjacent to the jacket 4 and over which the contact area 5 of the shielding sheath 3 is reversely drawn.
  • the contact area 5 extends over a bevel 10 of the head portion 7 and is adjacent to a circumferential surface 11 which conically increases in diameter toward the neck portion 8.
  • a web 12 projecting outward is provided at the head portion 7; the web 12 comprises a plurality of recesses 13 evenly distributed at its circumference.
  • a slotless shield 15 is disposed, in which a carrier 16 for contact pins 17 is arranged.
  • the shield 15 is of such type that it can be slipped and clamped onto the conical circumferential surface 11 of the head portion 7, with its entire circumference being in a close relationship to the head portion 7.
  • the reversed contact area 5 of the shielding sheath 3 is clamped between the shield 15 and the head portion 7.
  • the edge 18 of the shield 15 communicates with the web 12.
  • Lugs 19 project through the recesses 13. The lugs 19 are bent toward the head portion 7 after the shield 15 with its edge 18 has been pushed onto the head portion 7.
  • the shield 15 consists of metal. Owing to the stopper 6 and the shield 15, which are in a solderless, electrically conductive connection to the contact area 5, the wire strands 2 are located in a space 20 which is RF-shielded with respect to the circumference and to the cable 1. Any RF-window between the jacket 4 and the plug socket 15 is avoided, because the shield 15 sits closely at the stopper 6 and because of the solid construction of the stopper 6 in the region of its head portion 7 and the extension of its neck portion 8 to a region of the cable 1 in which, by the exposure of the shielding sheath 3, the shielding sheath 3 is definitely not shifted. In the region of the head portion 7, displacement of the shielding sheath 3 in its contact area 5 is not detrimental, since, at any rate, the shield 15 is positioned close to the stopper 6.
  • a plastic sheath 21 is sprayed around the sheath 15 and the stopper 6. If necessary, the space 20 may also be filled by injecting a plastic mass.
  • these parts may also be provided with threads.
